I wouldn't mind seeing the rule overturned for general usage or data. But I hope that voice calling continues to be prohibited. Sitting on a 6 hour flight listening to multiple people screaming into their phones over the sound of the engines would suck so bad. Its bad enough on a 15 minute bus ride.
Have a space by all means where people can talk, just make sure it's soundproof. I had someone sitting next to me on an hour long train ride, who, if she said "at end o' day" one more time, I would have killed her and pleaded justifiable homicide.
